GOSTs of sheets, wires, pipes, circles of 08X18T1 steel

Technical characteristics

Grade 08Cr18T1 refers to chromium alloys of ferrite class. It is melted in open arc electric furnaces. Production is regulated by the following GOST 5582-75 and 5632-72 and technical conditions: 14-1-1081-74; 14-1-4035-85 и 14-1-2421-78. Steel is used for the production of electric-welded pipes, as well as in food and commercial equipment, in the manufacture of cutlery and kitchen utensils, household appliances, consumer goods. The Ministry of Health permits the use of such steel for the manufacture of parts that are in contact with must, wine (up to 24 hours), in the manufacture of containers and equipment for the dairy industry, sugar beet industry and diffusion plants.

Heat treatment

Recommended hardening temperature is 1000-1100°C with subsequent cooling in water or air. This heat treatment contributes to the normalization of internal stresses in the alloy and increases the strength characteristics of parts. The metal is easy to shake out and forge. Cold-treated: the metal has high strength and ductility. During cold working, the steel is deformed and hardened similarly to 12X18H10T grade.

Advantages

Steel 08x18t1 has a high resistance to oxidation, ductility, easy deformation, the possibility of deep drawing, good weldability, which allows its use in the same equipment as the austenitic chromium-nickel grades. Low temperatures do not produce the viscosity changes characteristic of cold brittleness. Biological inertness makes the steel popular in food processing. In terms of its mechanical properties it is a stronger and harder material compared to 12X18H10T grade. The oxidation takes place above a temperature of 800 °C. The tarnish color is observed during heating in the temperature range from 550 to 800 °C.

The rate of corrosion

- In a humid atmosphere saturated with _NH3 and _{H2 S2}, up to 0.005 mm/year;

- in solution, _{H2 S2} with a saturation of 2.5 g/l - up to 0.0135 mm/year;

- in _NH3 aqueous solution, corrosion rate (t° 20 °C) up to 0.006 mm/year; at 90 °C - up to 0.097 mm/year;

- in a mixture of aliphatic hydrocarbons, (temperature 20-90 ° C) to 0.003 mm/year;

Welding

Arc welding is carried out by manual or automatic submerged-arc welding, 10X18N10T wire rods are used as an additive. During rapid cooling, the best weld quality is achieved. In order to protect the welds from intergranular corrosion, it is necessary to heat treat the parts after welding. If sheet thickness is small, resistance welding can be applied.
